Electronically steerable line array speakers allow perfect adaptation to the room architecture and acoustics.

Active, electronically steerable line array speaker, 24x 4“ neodymium speaker, digital 24-channel DSP amplifier integrated, 24 separate DSP channels, vertical sound dispersion, digitally controlled (beam angle: 0° to 90°), vertical sound inclination angle, digitally controlled (-40° to +40°), horizontal sound dispersion: 110°, aluminium housing in all RAL colours, length: 349 cm, weight: 25 kg. All connections are placed inside the housing of the LFI-350 behind a easy accessible service flap in front.

 

  • Electronically steerable, using integral amplifier and DSP technology
  • Individual control of beam and beam angle in realtime
  • TWO beam technology (2 dispersion beams possible)
  • Intuitive control software
  • Excellent sound and extremely dynamic speech and reproduction music
  • Aluminium designer housing in all RAL colours
  • Important features for system integration as per EN 60849 / DIN 0828 Regulations on Places of Assembly (alarm sound systems)
  • Monitoring and intelligent evaluation of all important device parameters

 

Linea Focus: active, electronically steerable line array speaker. The cream of sound technology. The vertical sound dispersion characteristics of the speaker can be directed towards a specific section of the audience using state-of-the-art digital technology and software from Fohhn without having to alter the speaker position mechanically. Ideal for large churches, cathedrals, railway stations, conference halls, airports, trade fair centres, etc.

 

Perfect integration
Thanks to the electronic control function, the speaker system can be mounted flatly on the wall or installed directly in the wall, allowing perfect integration into the room architecture.

 

TWO Beam Technology
The Linea Focus system with “two beam technology” developed by Fohhn can generate 2 dispersion beams in the vertical dispersion range. A speaker system can direct sound at a specific area of the dance floor or gallery as a result.

 

Side Lobe free Technology
This specially developed algorithm can suppress unwanted side lobes.

 

DSP and Software Technology
Multichannel Fohhn amplifier and DSP technology combined with control software developed by Fohhn gives you complete control of the beam angle, sound characteristics and dynamics.

Fohhn® DSP processor technology modulates the Linea Focus and Fohhn subwoofers perfectly. Digital Fohhn signal processors are integral components of active Fohhn subwoofers, Fohhn DSP amplifiers and Fohhn DSP controllers. DSP-controlled Fohhn devices can be controlled remotely from a central location in the room or on the stage via intuitive remote control units. Fohhn therefore offers a perfectly adapted sound system that fulfils all the requirements of a modern speaker system regarding design, sound quality and operating comfort in every respect.

 

Connections
All connections are placed inside the housing of the LFI-350/450 behind an easy accessible service flap in front. That means that all cables are implementing by the rear cable inlet into the housing. So the cables can be connected to the Phoenix teminals very comfortable from the front. Extraneous no cable is visibly. The internal cord grip guarantees a save operation.

 

Integration as per VDE 0828
Important features for system integration as per EN 60849 / DIN 0828 Regulations on Places of Assembly (alarm sound systems):

  • 2 independent line inputs with automatic priority and symmetrical transformers
  • fault message contact for simultaneous evaluation of the operating status
  • 24 volts emergency power operation
  • monitoring and intelligent evaluation of all important device parameters

 

Configuration
To configure the Linea Focus the Fohhn Audio Soft V3 is indispensable. For connecting the it to a PC the Fohhn-Net Adaptor NA-1 is necessary.

 

Wide range of application possibilities
Large churches, cathedrals, railway stations, conference halls, airports, trade fair centres, etc.

Electronically steerable active line source speaker

Powerful active, electronically steerable line source speaker with aluminium enclosure, equipped with 24 coated, long stroke 4” – drivers and digital 24-channel DSP amplifiers. Because of the application of neodymium chassis and an aluminium enclosure, the speaker remains light with only 25 kg. Perfectly suited for dynamic speech- and music transmissions in rooms with demanding acoustics, long reverberation times and challenging architecture. The 24 integrated digital amplifiers with 100W each generate acoustic pressure of maximal 133,5 dB. The speaker has a wide frequency range of 60Hz to 17kHz. The horizontal dispersion of 110° and the adjustable vertical sound inclination angle of 0° to 90° in steps of 1° allow an exact adjustment onto the audience. The inclination angle of the beam can be adjusted from + 40° to - 40° in steps of 0,5°. The Linea focus system can generate two dispersion beams and is therefore able to reach additional areas such as galleries. It is possible to high-pass filter the beams separately. Unwanted side lobes which occur because of interferences are suppressed effectively through a specially developed Optimize-Algorithm. The adjustment and monitoring of all parameters is controlled in real time with Fohhn Audio Soft V3.0. The handling is easy and intuitive done via mouse click. The dispersion of the speaker, the sound level and the frequency are graphically visualized. Two symmetrical transformers, independent line inputs, alive contact for an analogue evaluation of the operating status, 24V emergency current, control and intelligent evaluation of all important parameters. Optically appealing, slim and inconspicuous aluminium enclosure with rounded sides, available in black anodized or white matt varnish. Optional available in all RAL-colours. For the protection of the speaker chassis and the electronics, the enclosure is equipped with a ball impact resistant, extremely sound-permeable front grille, which is made of powder-coated steel as well as a moisture- and dust repellent acoustic fleece. Highly efficient Green Power supply with a maximum activity input of 10W in stand-by mode. 10 pieces M6 thread applications are integrated to the admission of system brackets. Connections: internal Phoenix terminals and a cable duct on the back. Specific brackets to assemble the system on ceilings, walls, traverses and stands are optionally available. Simulation data CAAD for EASE are in preparation.
